Drawing Shapes and Young Tablauex

I would like to draw a shape, in the sense of a young tableaux with arbitrary boxes missing.

A currently have the following, which allows me to draw skew tableaux, however I want the box containing c to be removed (with a gap in its place, not just an empty box)

\usepackage[enableskew]{youngtab}

\begin{document}

$\young(ab::cd,:efg)$

\end{document}

• Do you want a gap? Or an empty box? – caverac Mar 20 '18 at 13:32
• I am wanting a gap – 123 Mar 20 '18 at 13:47

This is a solution with ytableau

\documentclass[]{article}

\usepackage{ytableau}

\begin{document}

\ytableausetup{centertableaux}
\begin{ytableau}
a & b & \none & d \\
\none  & e &     f & g
\end{ytableau}

\end{document}
